The Williams FW42 was a Formula One racing car designed by Paddy Lowe, Doug McKiernan and Dave Wheater for the ROKiT Williams Racing team, to compete in the 2019 FIA Formula One World Championship. The car made its competitive debut at the 2019 Australian Grand Prix, driven by the reigning 2018 FIA Formula 2 Champion George Russell who was making his Formula One début; and Robert Kubica, who returned for his first racing season in Formula One since 2010, after recovering from life-threatening injuries suffered in a rally car accident in early 2011.
The car was notably suffered with a build quality problems, poor performance and reliability issues, making it the worst Williams car and the worst car of the entire 2019 grid.
